CAS No: 130650-09-8 is an organic compound, also known as Dimethyl oxalate, which is a colorless and odorless liquid often used in various industrial processes. It is an important intermediate for the synthesis of many pharmaceuticals, agrochemicals, and other chemicals.

Dimethyl oxalate is produced by the reaction of methyl formate and formic acid, and can be purified by distillation. Its molecular formula is C3H6O4 and molecular weight is 102.08. It is freely soluble in water, alcohol, ether and other organic solvents. The boiling point of Dimethyl oxalate is 99℃ and the freezing point is −18.7℃.

Dimethyl oxalate is mainly used as an intermediate in the production of agrochemicals and pharmaceuticals, and also as a solvent in chemical processes. It is also used in the synthesis of oxalic acid derivatives. It can also be used as a catalyst in chemical reactions, such as the production of isocyanates.

The safety of Dimethyl oxalate is mainly dependent on its concentration and exposure time, and it can cause irritation to skin, eyes, and respiratory tract when it is in contact with them directly or as a vapor. It should be handled with care, and protective clothing and equipment should be worn when handling it.
